CVE-2023-39192 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-10-15 N/A 6.7 MEDIUM
A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.
CVE-2023-39189 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-10-15 N/A 5.1 MEDIUM
A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
CVE-2023-32233 3 Linux, Netapp, Redhat 3 Linux Kernel, Hci Baseboard Management Controller, Enterprise Linux 2026-10-15 N/A 7.8 HIGH
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
CVE-2023-6606 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-10-14 N/A 7.1 HIGH
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
CVE-2023-6121 1 Redhat 1 Enterprise Linux 2026-10-14 N/A 4.3 MEDIUM
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
CVE-2023-5981 4 Debian, Fedoraproject, Gnu and 1 more 4 Debian Linux, Fedora, Gnutls and 1 more 2026-10-14 N/A 5.9 MEDIUM
A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.
CVE-2023-5178 3 Linux, Netapp, Redhat 5 Linux Kernel, Active Iq Unified Manager, Solidfire \& Hci Management Node and 2 more 2026-10-14 N/A 8.8 HIGH
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation.
CVE-2023-5156 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2026-10-14 N/A 7.5 HIGH
A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 49 Ubuntu Linux, Debian Linux, Fedora and 46 more 2026-10-14 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2023-4273 5 Debian, Fedoraproject, Linux and 2 more 12 Debian Linux, Fedora, Linux Kernel and 9 more 2026-10-14 N/A 6.0 MEDIUM
A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack.
CVE-2023-4004 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2026-10-14 N/A 7.8 HIGH
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-3773 4 Debian, Fedoraproject, Linux and 1 more 4 Debian Linux, Fedora, Linux Kernel and 1 more 2026-10-14 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data to userspace.
CVE-2023-3772 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2026-10-14 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.
CVE-2015-8126 9 Apple, Canonical, Debian and 6 more 21 Mac Os X, Ubuntu Linux, Debian Linux and 18 more 2026-10-14 7.5 HIGH N/A
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.
CVE-2023-3212 5 Debian, Fedoraproject, Linux and 2 more 14 Debian Linux, Fedora, Linux Kernel and 11 more 2026-10-14 N/A 4.4 MEDIUM
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
CVE-2023-2953 4 Apple, Netapp, Openldap and 1 more 16 Macos, Active Iq Unified Manager, Clustered Data Ontap and 13 more 2026-10-14 N/A 7.5 HIGH
A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function.
CVE-2023-1652 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-10-14 N/A 7.1 HIGH
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem.
CVE-2023-1206 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-10-14 N/A 5.7 MEDIUM
A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%.
CVE-2023-1095 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-10-14 N/A 5.5 MEDIUM
In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.
CVE-2025-14087 2 Gnome, Redhat 2 Glib, Enterprise Linux 2026-10-14 N/A 5.6 MEDIUM
A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
